Figure 6From: Regenerative defect in vastus lateralis muscle of patients with chronic obstructive pulmonary diseaseSkeletal myosin fast twitch protein accumulation during myogenesis in satellite cells isolated and cultured from healthy subjects (white bars; n = 9) and patients with COPD (black bars; n = 8). Protein extraction was performed daily after initial differentiation. Signal analysis was calculated by densitometry and reported over a positive control. When a is present: statistically significant difference from control (ANOVA; p < 0.05).Back to article page
